Pyroman Posted March 18, 2010 Posted March 18, 2010 I'm going between 2 switches do i need a regular or xover cable?
tmcd35 Posted March 18, 2010 Posted March 18, 2010 regular. You only need crossover of between two pc's or two hubs without auto-sensing ports.
Chunky Posted March 18, 2010 Posted March 18, 2010 If its a 100 meg switch, technically, you can use either, as they will auto-neg. If its a gigabit, you'll need a standard straight cable. Chunks
Pyroman Posted March 18, 2010 Author Posted March 18, 2010 Cheers, a squirrel has eaten through the network cable on the roof and i need to put a new end on it 1
webman Posted March 18, 2010 Posted March 18, 2010 Cheers, a squirrel has eaten through the network cable on the roof and i need to put a new end on it I'd go nuts if any squirrel ate away at our cables. 2
tmcd35 Posted March 18, 2010 Posted March 18, 2010 Cheers, a squirrel has eaten through the network cable on the roof and i need to put a new end on it well, it made me chuckle - sorry. EDIT: @Webman - I was avoiding the obvious
webman Posted March 18, 2010 Posted March 18, 2010 EDIT: @Webman - I was avoiding the obvious It had to be done. I'll get me coat now
finbar3 Posted March 18, 2010 Posted March 18, 2010 a what type of switch is it b if it has a up link and down use them c some old switches you can turn the links off d if it a cheap switch just plug them in c if it has dhcp dont connect to your lan
Hightower Posted March 18, 2010 Posted March 18, 2010 If its a 100 meg switch, technically, you can use either, as they will auto-neg. If its a gigabit, you'll need a standard straight cable. Auto negotiation has nothing to do with x-over or straight through cables Chunky (AFAIK). Auto negotiation is the process where the switch can determine things like speed and duplex of the link instead of having to set these properties manually.

Pyroman Posted March 18, 2010 Author Posted March 18, 2010 new update on this. allegedly the media technician needed some cable and asked the site manager for some ladders and chopped the cable up because he thought it was unused
srochford Posted March 18, 2010 Posted March 18, 2010 Is the person who put exposed cat 5 cable on the roof still alive ???
Pyroman Posted March 18, 2010 Author Posted March 18, 2010 both media technician and imanginary squirrel are okay as the tech isn't in today and the squirrel doesn't exist. I had a hard time believing squirrel story when i went up onto the roof and it was a clean cut and 30ft of cable was missing. I know squirrels are athletic but pulling 30ft of cable through a hole in the wall that was coiled and plugged into a switch on the other side of the wall is a bit much to believe.
sippo Posted March 18, 2010 Posted March 18, 2010 Bet it was this squirrel: [ame=http://www.youtube.com/watch?v=aY9GBl7UmVs]YouTube- Carling Black Label - Mission Impossible (squirrel)[/ame] Can't beat the classics!
waldronm2000 Posted March 18, 2010 Posted March 18, 2010 Xover between 2 switches. The ports should auto-MDIX, but why rely on it when you could just use the correct cable in the first place.
Pyroman Posted March 18, 2010 Author Posted March 18, 2010 oh and the switch it was going into had a little button to go from straight to X-over so no worries there. thanks for advice everyone

Auto negotiation is the process where the switch can determine things like speed and duplex of the link instead of having to set these properties manually. I'll think you'll find that speed and duplex depend very much on whether it's a straight or crossover. During the auto-negotiation process connections are made between the 2 devices at the highest speed possible by the hardware. If the hardware (inc the cable) aren't capable then the connection will fail. The OP asked whether it had to be straight or crossover, and if it mattered. If it was a gigabit connection he wanted, then yes, it matters a lot, as Gigabit (on the whole) is not spec'ed to allow a standard crossover cable - though I've seen a cable pin diagram that does work. Using a standard crossover cable would cause autonegotiation to drop down to 100meg (full or half). Chunks

YorkshireTechie Posted March 18, 2010 Posted March 18, 2010 how long did you have it working on the roof open to the elements?
sparkeh Posted March 18, 2010 Posted March 18, 2010 how long did you have it working on the roof open to the elements? Squirrels are used to working in the outdoors.
